the current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of eremostachys azerbaijanica (labiatae) as well as analyzed the potent extracts using gc-ms. extracts of e. azerbaijanica in n-hexane, dichloromethane (dcm) and methanol (meoh) were prepared using a soxhlet apparatus. the antioxidant activity of the extrac...
Background: We evaluated the feasibility and accuracy of 11C–choline PET-CT/TRUS fusion-guided prostate biopsy in men with persistently elevated PSA and negative mpMRI or contraindication to MRI, after previous negative biopsy. Clinical data were part of a prospective on-going observational clinical study: “Diagnostic accuracy of target mpMRI/US fusion biopsy in patients with suspected prostate...
Region-based artificial attention constitutes a framework for bio-inspired attentional processes on an intermediate abstraction level for the use in computer vision and mobile robotics. Segmentation algorithms produce regions of coherently colored pixels. These serve as proto-objects on which the attentional processes determine image portions of relevance. A single region—which not necessarily ...
The present study was designed to confirm the wide traditional use of treating pain with Salix canariensis, an endemic species of the Macaronesian region. The active compounds were identified. Pharmacological activities were explored in experimental animals by acetic acid-induced writhing, formalin and Levy's tests, and bioactive compounds were identified after a bio-guided fractionation of the...
Reliable vision in dim light depends on the efficient capture of photons. Moreover, visually guided behaviour requires reliable signals from the photoreceptors to generate appropriate motor reactions. Here, we show that at behavioural low-light threshold, cockroach photoreceptors respond to moving gratings with single-photon absorption events known as 'quantum bumps' at or below the rate of 0.1...
Engineering mature tissues requires a guided assembly of cells into organized three-dimensional (3D) structures with multiple cell types. Guidance is usually achieved by microtopographical scaffold cues or by cell-gel compaction. The assembly of individual units into functional 3D tissues is often time-consuming, relying on cell ingrowth and matrix remodeling, whereas disassembly requires an in...
Plasma drawn from 22 patients with a broad range of von Willebrand factor (vWF) levels, including one patient with rare, severe type III von Willebrand's disease, was used to investigate the adaptability of the Bio/Data Corp. vW Factor Assay, a ristocetin cofactor-based kit developed for use with a platelet aggregometer, to a macroscopic platelet agglutination technique. The results were compar...
BACKGROUND The sensitivity and selectivity of traditional methods limits ultramicro detection of proteins. Bio-barcode amplification detection methods based on nanotechnology enables ultramicro detection of protein. However, bio-barcode amplification detection depends on the oligonucleotides being fixed on a glass chip. It also requires specialized equipment, which limits its application. We in...
We evaluated four spectrophotometric methods for suitability in determining total protein in human milk samples. Results were compared with those by an established method for the determination of total nitrogen (micro-Kjeldahl). Values for total protein by all four methods significantly correlated with micro-Kjeldahl. For the biuret assay, Lowry-Peterson assay, Bio-Rad Coomassie Blue assay, and...
introduction: lung cancer is one of the leading causes of cancer related deaths in the world. the incidence of lung cancer is increasing in india and there is a need to understand the natural history of this disease. aim of the study: to study the clinico- pathological- radiological profile of patients diagnosed with lung cancer from january 2013 to may 2015 at a tertiary care teaching hospital...
